SEEDING ATTACHMENT FOR DISK HARROWS.

SPECIFICATION forming part of Letters Patent No. 634,997, dated October 17, 1899.

Application filed November l2, 1898. Serial No. 696,320. (No model.)

'fo @ZZ whom, t 11mg/ concern:

Be it known that we, JONATHAN Jonson Roenes and OLIVER SYLVESTERKENNEDY, citizens of the United States, residing at Fort I'Vorth, in the State of Texas, haveinvented certain new and useful Improvements in Seeding Attachments for Disk Harrows; and we hereby declare that the following is a full, clear, and exact specification of the saine.

Our invention relates to seeding attachments for disk harrows; and the same is designed more particularly as an improvement upon the structure disclosed by Letters Patent No. 406,147, issued to us jointly on July 2, issn.

The object of the present improvements is lo simplify the construction, promote the efliciency of the appliances for distributing the seed, retain the grain-tubes securely in place, and enable the devices to be adjusted to regulate the discharge of grain within desirable limits. i

With these ends in'view the invention consists in the novel construction, combination, and arrangement of parts, which will be hereinafter fully described and claimed.

In the drawings, Figure l is a plan View of a combined harrow and planter embodying our improvements. 2 is a rear elevation, on an enlarged scale, partly broken away and in section, of one of the hoppers and harrowsections. Fig. 3 is a vertical longitudinal scction through one of the barrow-sections and theseedingdevicesassociatedtherewith. Fig. a is a sectional elevation taken centrally through the machine and showing one harrow-section and the seeding devices thereon in end View.

The same letters of reference are used to indicate like and corresponding parts in the drawings.

The general structure of the machine is similar to the combined barrow and planter disclosed by our former patent, to which reference has been made, and it includes the draft tongue A7 provided with the crossbea-m B.

C is the seat-bar, fixed to the framework and carrying a seat at its upper rear end.

D D are the draft-links, `connected to the beam B and the outer ends of the harrowwhich are connected to the inner endsof the harrowa-xles, said movable links being connected pivoially with a lever F, which is fulcrumed on the draft-beam A. The harrowaxles G are arranged on opposite sides of the line of draft andV inclined reversely to Aeach other. Said axles carry the harrow--disks H, arranged in gangs in the usual way, and over these barrow-disks are the horizontal weightboxes I, said weight-boxes being connected by suitable standards with the axles of the harrow-disks. Extending rearwardly from the weight-boxes are the frames a., each supporting a seed-hopper d, said seed-hopper being thus disposed in rear of the gang of harrowdisks and the weight-box and in a horizontal plane above the latter. Each frame, with the seedhopper, is braced by the employment of arms b, which are attached to the frame and connected with the barrow-axle or the standards which support the weightbox I. Each hopper is provided near its rear edge with a series of grain-openings t' in the bottom thereof, whereby'the grain-openings lie at the rear of the hopper instead of centrally therein, as disclosed by our former patent. To the under side of each hopper is secured a series of seed-cups y, which are located near the rear edge of the hopperin positions to register with the grain-openings lin the bottom thereof, each seed-cup having a short nozzle extending from the under side thereof. A force-feed shaft, square in cross-section, extends through the entire se- `ries of seed-cups on each hopper, said shaft being journaled in proper bearings provided by the seed-cups, and to said shaft is tted a series of force-feed wheels h. A feed-wheel is located in each seed-cup to operate in the chamber thereof and to rotate with the shaft, so as to regulate the quantity of grain which may pass through the opening t to the spout or tube g. The feed-Wheels constituting the series on each shaft are connected thereto so axles, and E E are the movable draft-links,

as to move endwise with the shaft and vary ICO .charged by the feed-wheels through the seed'- cups and the grain spouts or tubes. The inner end of each force-feed shaft extends beyond the corresponding end of the hopper for the reception of asprocket-wheel 7c, (see Fig. 4,) which is preferably fitted slidably to the polygonal shaft. As a means for adjusting the feed-shaft and the Wheels thereon we provide a segment P and lever n. The segment is fixed to the rear side of the seed-hopper in position to receive the fulcrum 0, which attaches the lever n to the segment and the seed-hopper. This lever is fulcrulned at a point intermediate of its length, and its lower end is pivoted to a link or arm m, which connects with the inner end of the force-feed shaft in a suitable way. The force-feed shaft is free to rotate, but the link 'm is connected with .this shaft vso as to move it and the series of feed-wheels endwise.

A rotary agitator-shaft 3 is jou rnaled in proper bearings in the end walls of the seedhopper, said shaft extending through the seed-hopper in the vertical plane of the openings z' in the bottom thereof. The shaft carries a series of fingers a, which are fastened to said shaft in positions to sweep over the grain-openings i in the bottom of the hopper, the alternate lingers on the shaft extending in opposite directions therefrom, as shown by Fig. 2. One end of the agitatorshaft eX- tends from the inner end of the seed-hopper to receive a sprocket-Wheel t, and as the agitator-shaft is in the Vertical plane of the forcefeed shaft the sprocket-wheels t t on the two shafts lie directly one above the other. The axle of each gang of barrow-disks is provided at its inner end with a sprocket w, with which engages an endless sprocket-chain fu, the latter also engaging with the sprocket-Wheelst if, as shown by Fig. 4f, so that the motion of the axle G when the machine is in operation will be communicated by the chain to the force-feed shaft and the agitator-shaft, thereby rotating both shafts from a common source of power.

The grain tubes or spouts g are expanded or slipped over the nozzles on the lower end of the seed-cups y, as shown by Fig. 3, and the series of grain-tubes on each hopper have their lower ends curved toward the gang of harroW-disks, so as to terminate in proper relation thereto. With each seed-tube is engaged a clip n', the latter being attached to the lower end of a hanger N, which is secured in a suitable Way to the rear side of the seed` hopper. The hangers and clips retain the seed-tubes in proper positions, while allowing them tomove or play within certain desirable limits. v

Changes may be made in the form and proportion of some of the parts, While their essential features are retained and the spirit of the invention embodied. Hence we do not desire to be limited to the precise form of all the parts as shown, reserving the right to vary therefrom.

Having thus described the invention, what we claim is l. A combined harrow and seeder comprising a suitable frame, the axles carrying the gangs of barrow-disks and each axle provided with a sprocket-pinion, the seed-hoppers having the seed-cups, a force-feed shaft extending through the cups and provided with the feed -wheels and the sprocket, an agitatorshaft extending through the hopper and having the fingers and the sprocket-wheel, and endless sprocket-chains connecting the harroW-axles with the force-feed shafts and the agitator-shafts, substantially as described.

2. A combined harrow and seeder comprisying a frame, the axles carrying the gangs of grain-tubes t-ted to the nozzles of the seed-4 cups, and hangers attached to the hoppers and provided with clips which engage With the grain-tubes, substantially as described.

In testimony that we claim the foregoing as our invention we have hereunto affixed our signatures in the presence of two Witnesses.
